Problem summary
**************************************************************** * USERS AFFECTED: Users of IBM Caching Proxy SSL * **************************************************************** * PROBLEM DESCRIPTION: Improve the default cipher suites for * * SSLv3, TLSv1.0, TLSv1.1, and TLSv1.2 in * * Caching Proxy to remove several weak * * ciphers. * **************************************************************** * RECOMMENDATION: * **************************************************************** Improve the default cipher suites for SSLv3, TLSv1.0, TLSv1.1, and TLSv1.2 in Caching Proxy to remove weak ciphers such as 3DES. The new default ciphers have been listed below: SSLv3 / TLSv1.0 / TLSv1.1: * 2F - TLS_RSA_WITH_AES_128_CBC_SHA * 35 - TLS_RSA_WITH_AES_256_CBC_SHA TLSv1.2: * 9C - TLS_RSA_WITH_AES_128_GCM_SHA256 * 9D - TLS_RSA_WITH_AES_256_GCM_SHA384 * 3C - TLS_RSA_WITH_AES_128_CBC_SHA256 * 3D - TLS_RSA_WITH_AES_256_CBC_SHA256 * 2F - TLS_RSA_WITH_AES_128_CBC_SHA * 35 - TLS_RSA_WITH_AES_256_CBC_SHA
Problem conclusion
The default ciphers for Caching Proxy have been modified. The new defaults are listed below for each protocol. SSLv3 / TLSv1.0 / TLSv1.1: * 2F - TLS_RSA_WITH_AES_128_CBC_SHA * 35 - TLS_RSA_WITH_AES_256_CBC_SHA TLSv1.2: * 9C - TLS_RSA_WITH_AES_128_GCM_SHA256 * 9D - TLS_RSA_WITH_AES_256_GCM_SHA384 * 3C - TLS_RSA_WITH_AES_128_CBC_SHA256 * 3D - TLS_RSA_WITH_AES_256_CBC_SHA256 * 2F - TLS_RSA_WITH_AES_128_CBC_SHA * 35 - TLS_RSA_WITH_AES_256_CBC_SHA 3DES (0A) ciphers can be re-enabled using the following directives as needed: V3CipherSpecs 2F350A TLSV11CipherSpecs 2F350A TLSV12CipherSpecs 9C9D3C3D2F350A This fix is targeted for IBM Caching Proxy fix packs: - 9.0.0.8 - 8.5.5.14 - 8.0.0.15
